Does The Color Of Light Affect Plants Growth

An Overview of Light Colors and Wavelengths

Every light spectrum is characterized by wavelengths. The wavelength of light can be described as the horizontal distance between the two peaks of the light wave. Visible light or visible spectrum is the distance of the electromagnetic wave we can see with our eyes, commonly extending from about 400 nm (violet) to 700 nm (red).

Plants do not have eyes but instead rely on their chlorophyll - a group of specialized cells that detect and respond to light energy. They can only detect wavelengths that fall within the ultraviolet radiation (260-380nm) and the visible portion of the light spectrum (380-740 nm).

Colors of light that fall in this range include: 

• Violet: 380-450 nm
• Blue: 450-495 nm
• Green: 495-570 nm
• Yellow: 570-590 nm
• Orange: 590-620 nm
• Red: 620-740 nm

What Color Of Light Is Best For Plant Growth?

The visible part of the light spectrum or the visible light spectrum comprises PAR (photosynthetically active radiation). During photosynthesis, plants absorb this radiation to produce sugars required to grow major parts, including roots, stems, and leaves. However, various wavelength ranges within the visible light spectrum affect plants differently. Two of the most important colored lights for your plant are red and blue. 

• Blue Light: Blue light is particularly important during the early stages of a plant's life, such as the seedling stage. When plants receive strong concentrations of blue light, it acts as a signal for them to sprout and develop robust root systems. This is essential because healthy roots provide the foundation for the plant's overall growth and ability to absorb water and nutrients from the soil. 
• Red Light: Red light has a multifaceted role in a plant's growth cycle, especially during the flowering stage. Certain specific wavelengths of red light trigger the production of a hormone within the plant's vegetation. This hormone acts to prevent the breakdown of chlorophyll. With more chlorophyll preserved, the plant can generate more nutrients through photosynthesis. This leads to healthier, taller plants with an abundance of leafy vegetation. 

Additionally, the following lights also play a role during the plant growth stage: 

• Violet or purple light, with its shorter wavelength and higher energy, can support the growth of a plant's leafy parts.
• Green light is mostly reflected by plants (making them appear green), but a small amount is absorbed during photosynthesis.
• Yellow and white light have minimal effects on plant growth.

To make a brief summary, blue light boosts a strong root system during the first growth phase and red light contributes to satisfying flowering and fruiting.
